AI Assistant 2026.1 Help

Code completion

Cloud completion powered by AI Assistant can autocomplete single lines, blocks of code, and even entire functions in real time based on the project context. The generated code is similar to how you would write code, matching your style and naming conventions.

Completion is available not only for code but also in commented lines, AI Chat, and commit messages. You can configure where you want to receive completion suggestions.

Work with cloud completion

To invoke code completion suggestions:

  1. Start typing in the editor, AI Chat, or Commit Message field. The suggestions start to appear as you type.

    AI-generated code suggestion
    AI-generated code suggestion in AI Chat
    AI-generated code suggestion for commented code
    AI-generated commit message

    You can also trigger the code completion by pressing Alt+Shift+\.

  2. To apply the suggestion:

    • Press Tab to accept the entire suggestion. You can configure a different shortcut for this action.

    • Press Ctrl+Right to accept a suggestion word by word.

    • Press End to accept a suggestion line by line.

    To reject the suggestion, press Escape. Alternatively, just continue typing or change the caret position either with the arrow keys or by a mouse click.

Configure cloud completion

The cloud completion option is enabled by default. To configure the way it works, press Ctrl+Alt+S to open the settings and go to Editor | General | Code Completion | Inline.

Enable inline completion

In this section, you can enable or disable the inline code completion feature and define which language models you want to use for inline completion:

Enable inline completion

Item

Description

Enable inline completion using language models

Enable inline code completion and select the models that you want to use for it:

  • Local – code completion relies on a locally run deep learning model to provide suggestions. The models can be downloaded for supported languages manually.

    This setup is available for use when the AI Assistant plugin is not installed.

  • Cloud and local – code completion relies on both locally run and cloud models to provide suggestions.

  • Cloud – code completion relies only on a cloud model to provide suggestions.

the Behavior section

Item

Description

Completion policy

This option allows you to control how many code suggestions you receive and how strictly they are filtered for accuracy and relevance.

Select the number of suggestions you want to receive:

  • Creative – provides more extensive, open-ended suggestions by turning off all filters, allowing even incomplete or speculative code to encourage experimentation.

  • Balanced – delivers a moderate number of suggestions. Softer filters allow for more variety while still prioritizing relevance.

  • Focused – the default setting. Offers brief, precise suggestions by applying strict filters that exclude potentially incorrect code.

Enable suggestions in Code Comments using cloud models

Enable to receive suggestions in code comments.

Enable multi-line suggestions
